contact usthe tailing, the flotation and the concentrate. For example coal mines (or mines of other materials) have to deal with the problem of disposing of the uneconomic material, by-product of the coal production. Especially, Matec machines can dewater the waste fines suspended in water, recovering, cleaning water and eliminating tailing ponds.

contact us· Underground transfer dams form an integral part of the water management systems of a mine. The purpose of the transfer dams in underground mine water management is to receive and transfer dirty water from the stopes to the mine surface.. The dirty water is clarified and treated if necessary (e.g. pH adjustment) before it is stored in surface water dams.
contact us· The simplicity of the approach makes it a viable proposition for use in continuous mining. The absence of a fan, dust collection equipment, water eliminators, etc., reduces the required maintenance. If a closed circuit is established to collect the dirty water and clarify it, small amounts of water can suppress large quantities of dust.
